Self-hosting (compilers)In computer programming, self-hosting is the use of a program as part of the toolchain or operating system that produces new versions of that same program—for example, a compiler that can compile its own source code. Self-hosting software is commonplace on personal computers and larger systems. Other programs that are typically self-hosting include kernels, assemblers, command-line interpreters and revision control software.
High-level programming languageA high-level programming language is a programming language with strong abstraction from the details of the computer. In contrast to low-level programming languages, it may use natural language elements, be easier to use, or may automate (or even hide entirely) significant areas of computing systems (e.g. memory management), making the process of developing a program simpler and more understandable than when using a lower-level language.General-purpose programming languageIn computer software, a general-purpose programming language (GPL) is a programming language for building software in a wide variety of application domains. Conversely, a domain-specific programming language (DSL) is used within a specific area. For example, Python is a GPL, while SQL is a DSL for querying relational databases.
LLVMLLVM is a set of compiler and toolchain technologies that can be used to develop a frontend for any programming language and a backend for any instruction set architecture. LLVM is designed around a language-independentintermediate representation (IR) that serves as a portable, high-level assembly language that can be optimized with a variety of transformations over multiple passes. The name LLVM originally stood for Low Level Virtual Machine.
Ruby (programming language)Ruby is a general-purpose programming language designed with an emphasis on programming productivity and simplicity. In Ruby, everything is an object, including primitive data types. Development of the language began in the mid-1990s by Yukihiro "Matz" Matsumoto in Japan. Ruby is interpreted, high-level, and dynamically typed; its interpreter uses garbage collection and just-in-time compilation.
Compiled languageInformally, a compiled language is a programming language that is usually implemented with a compiler rather than an interpreter. Because any language can theoretically be either compiled or interpreted, the term lacks clarity: compilation and interpretation are properties of a programming language implementation, not of a programming language. Some languages have both compilers and interpreters.
Object-oriented programmingObject-oriented programming (OOP) is a programming paradigm based on objects – software entities that encapsulate data and function(s). An OOP computer program consists of objects that interact with one another. An OOP language is one that provides object-oriented programming features, but as the set of features that contribute to OOP is contested, classifying a language as OOP – and the degree to which it supports OOP – is debatable.Type inferenceIn type theory, type inference (sometimes called type reconstruction) is the automatic detection of the type of an expression. These include programming languages and mathematical type systems, but also natural languages in some branches of computer science and linguistics.TIOBE indexThe TIOBE programming community index is a measure of popularity of programming languages, created and maintained by TIOBE Software BV, based in Eindhoven, the Netherlands. TIOBE stands for The Importance of Being Earnest, the title of an 1895 comedy play by Oscar Wilde, to emphasize the organization's "sincere and professional attitude towards customers, suppliers and colleagues".
Type systemA programming language consists of a system of allowed sequences of symbols (constructs) together with rules that define how each construct is interpreted. For example, a language might allow expressions representing various types of data, expressions that provide structuring rules for data, expressions representing various operations on data, and constructs that provide sequencing rules for the order in which to perform operations.
Apache LicenseThe Apache License is a permissive free-software and free and open source software license written by the Apache Software Foundation (ASF). It allows users to use the software for any purpose, to distribute it, to modify it, and to distribute modified versions of the software under the terms of the license, without concern for royalties. The ASF and its projects release their software products under the Apache License. The license is also used by many non-ASF projects.
Free and open-source softwareFree and open-source software (FOSS) is software available under a license that gives users the right to use, share, modify, and distribute the software — modified or not — to everyone and provides the means to exercise those rights using the software's source code. FOSS is an inclusive umbrella term encompassing free software and open-source software.*As an Amazon Associate I earn from qualifying purchases.
